9. Developers are modding the Valve Index with fans to keep the headset cooler. Jamie Feltham reports that in his experience the HMD became rather hot, and although this was not enough to cause concern, it did lead to some fogging issues. To combat this, some owners have taken to tinkering with the hardware using the files that Valve provided last month (then withdrew, and finally restored). One of the most popular designs shared on Reddit involved removing the headset’s front faceplate and fitting small fans inside. These are then connected up to the USB port on the front of the device to power them. – UPLOADVR
